# etex is something for eclipse
# Building with --disable-xindy as it requires libffcall
# "kpsewhich -var-value=SELFAUTOPARENT" strips two trailing directories 
#   from the location of the binaries, and this value is used by many
#   things in TeXLive (including tlmgr); therefore, it seems best to just
#   "go with the flow" and use "--enable-multiplatform" so the symlinks
#   that are automatically created will be correct...
# Building with "--without-system-xpdf" because poppler API changes too often
# Re ^^ let's try again with the system poppler library
